Micrometer: A Unit of Length

Definition of the micrometer

The micrometer, also known as the micron, is a unit of length in the International System of Units (SI) that equals one millionth of a meter. Its symbol is µm.

History of the micrometer

The term micron and the symbol µ were officially accepted for use in isolation to denote the micrometer in 1879, but officially revoked by the International System of Units (SI) in 1967. This became necessary because the older usage was incompatible with the official adoption of the unit prefix micro-, denoted µ, during the creation of the SI in 1960. In the SI, the systematic name micrometre became the official name of the unit, and µm became the official unit symbol.

How to convert micrometer

The micrometer can be converted to other units of length using simple multiplication or division by powers of 10. For example, one micrometer is equal to 0.001 millimeters, 0.000001 meters, or 0.000000001 kilometers in the SI system. One micrometer is also equal to 0.000039 inches, 0.0000033 feet, or 0.00000062 miles in the US standard system.

Where micrometer is used

The micrometer is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibers. The width of a single human hair ranges from approximately 20 to 200 µm

The micrometer is used in different countries and applications for various purposes. For example:

• In Canada, the micrometer is used to measure air quality by monitoring the concentration of particulate matter (PM) in the atmosphere. PM2.5 refers to particles that are less than 2.5 micrometers in diameter, which can penetrate deep into the lungs and cause health problems.
• In Japan, the micrometer is used to measure the thickness of paper and film products. The standard paper size A4 has a thickness of about 100 µm, while a typical plastic wrap has a thickness of about 10 µm.

Example conversions of micrometer to other units

Here are some sample conversions of micrometer to other units:

• 1 µm = 0.001 mm
• 1 µm = 0.000001 m
• 1 µm = 0.000000001 km
• 1 µm = 0.000039 in
• 1 µm = 0.0000033 ft
• 1 µm = 0.00000062 mi
• 1 µm = 10^^-6 m

Meter - Unit of Distance / Length

Unit Symbol / Abbreviation: m

Where the unit used in the World:

The meter is used as a unit to measure medium distances or lengths.
It's a standard measure for short distances (up to 1 km long), in real estate and construction, supply materials, vehicle and aircraft dimensions, short geographical distances and directions in most countries excluding the USA where foot and yard are still widely used for this purpose.
The meter is widely used in most countries and is the official unit for medium lengths and distances (for example, road signs in continental Europe show maximum vehicle hight in meters). Primary exceptions are the United States of America, and some countries where feet and yards are used in limited extent: the United Kingdom and Canada, where the yard remains in limited use as a part of imperial system (for example, yards are used on road signs for shorter distances in the United Kingdom and feet are widely used in construction and real estate in Canada).

Definition of the Unit:

The meter (metre in UK spelling) is a unit of length/distance in the metric system (SI Unit system) equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983).

1 m is equivalent to 3.28084 ft or 0.000621371 miles.

History of the Unit:

As a result of the French Revolution in 1789, the old units of measure that were associated with the monarchy were replaced by the new units. The new unit of length was introduced which became known as the meter. In 1795 the meter was defined as 1/10,000,000 part of the quarter of a meridian, passing through Paris. The meter gained popularity in continental Europe during the nineteenth century, particularly in scientific field, and was officially adopted as an international measurement unit in 1875. In 1960 the meter was defined as 1,650,763.73 wavelengths of light from a specified transition in krypton-86. In 1983 the final definition of meter was accepted as length of the path travelled by light in a vacuum in 1/299,792,458 of a second.

Where it's used:

The meter is commonly used in different trades and industries (for examle in machinery manufacturing), on road signs to indicate vehicle hight limits, the distance to short travel to a given location (for example in automotive GPS navigation voice prompts), on maps to indicate small scale, for vehicle, vessels and aircragt dimensions in industry and trade. It is also the most popular unit for describing the retail estate distances and measurements (room sizes, floor measurements and so on).

Equivalents in other units and scales:

• 1 m = 1000 millimeters (mm)
• 1 m = 100 centimeters (cm)
• 1 m = 10 decimeters (dm)
• 1 m = 0.001 kilometers (km)
• 1 m = 3.28084 feet (ft)
• 1 megameter = 1000000 m
• 1 gigameter = 1000000000 m
• Units of length in the metric SI system are based on multiples or fractions of a meter.
• There are measurements of length/distance in the metric SI system greater than a meter that can be expressed in terms of metres.

1 m is equivalent to 3.28084 ft or 1.09361 yd.

The meter is a unit of length in the metric SI system and is equivalent to the length of the path travelled by light during a time interval of 1/299,792,458 of a second (in vacuum, defined since 1983).
